Claims. (Cl. 15-250) rihis invention relates to clips" or" connectorsapplied to windshield wiper blades for attaching the end of theoscillating windshield wiper arm. The principal purpose of the`invention is to provide a simple and economical form of connector whichmay be suitably attached to the wiper blade and which is so constructedthat it will receive and eiectually retain the free end of severalstandard types of wiper arms which may be selectively connected to thewiper blade by the use of the improved clip. A Y

More specifically, it is'an object of this invention to provide abox-like clip or connector having its ends p-referably'fastened to theback of the wiper blade and having its top formed with a plurality ofopenings for the reception of conven- Jtional wiper arms of more thanone'type; and comprising a spring member disposed within thev connectorand adapted to prevent accidental removal of the end of a wiper arminserted in the selected opening of the clip. l

Recommended embodiments of the invention are illustrated in theaccompanying drawings, but

it will be understood that the'structural details' of the clips orconnectors shown and described herein may be varied without departing`from the essence of this invention as'defined in the ap-v pendedclaims. In the drawings,

Fig. l is a fragmentary planview of aY wiper blade with a preferred formof the improved clip attached thereto;

Fig. 2 is a side elevation of Figi 1; i u

Fig. 3 is a transversesectiononv line 3-"-3Vof Fie". 2;

Figs. 5 and 6 are central longitudinal sections through the wiperblacleand the attached clip,.

respectively indicating the manner in which ther ends of the hook-typearm-the stud-typearm,

and the pin-type arm are'remov'ablyconnected 50 in the particularembodiment chosenior the to the modified form of clip;

purpose or illustration in Figs. l'to 6 inclusive, the improved clipcomprises a box-like member, preferably made in one piecebylstampin'gand bending a metal4 sheet to'form aconnector having-i` ends II and I2,a top generally indicated at I3, and sides Ill and I 5 extending fromend to end of the device. It will be understood that the sides and endsof the clip may be bent downwardly from the top part to form thebox-like structure. The ends I I and I2 are respectively provided withbottom tabs I6 and I'I, which pass through and are crimped beneathsuitable openings in the metal shell or backing I8 of the wiper bladeE9, to secure the clip to the blade, but other means of fastening theparts together may obviously be provided. It will also be understoodthat the ilexible rubber wiper blade I9 may be of any desired form orconfiguration and may be held in the shell or backing I8 in any desiredmanner, inasmuch as the particular structure of these elements isimmaterial to this invention.

The top of the connector is provided with openings 253 and 2l, adjacentthe ends II and I2 respectively, the transverse opening 2! communieatingwith downwardly extending notches or slots 22 in the sides I4 and I5. Aportion 23 of the top I3 bridges the space between the opening 2l andthe clip end I2. The top preferably has another opening 24 spacedinwardly from the notched opening V2 I, 22.

Intermediate the openings 20 and 24, the top of the clip is curved orbowed downwardly at 25, and the inward side of said bowed portion isprovided with an aperture 26 therethrough. A leaf-type spring 21 isdisposed within the clip or connector with its central portion restingon the blade back I3, as best shown in Figs. 4 to 6. One end of saidspring is looped at 28 to provide an end portion 29 extending upwardlyand inwardly of the boxlike clip and normally engaging the bottom of thebowed or depressed portion 25 of the clip top, vas shown in Figs. 5 and6. The opposite end of the spring is curved upwardly and inwardly andterminates in a reverse bight 3U which normally engages the underside ofthe top portion 23, with the bight projecting into the space between thenotches 22, to provide a'latch element as hereinafter described. Y

The spring is inserted within the clip or connector before the latter isattached to the wiper blade, and its loosely therein, being held inposition by theresilience of its respective rearwardly bent ends whichyieldingly engage portions of .the connector top, as aforesaid.

, 3 top and the spring end 29, until the stud 32 engages in the aperture26. Such engagement is yieldingly maintained by the spring end, as willbe apparent.

As shown in Fig. 5, the end 33 of a pin-type wiper arm is attached tothe clip by inserting its cross pin 34 into the transverse opening 2land the side slots 22, beneath the latch element 30 of the opposite endof the spring 2l. It is apparent that the latch will yield uponinsertion of the pin 34, and will spring back to normal position whereit obstructs accidental removal of the pin from the slots 22.

As shown in Fig. 6, the end 35 of a hook type arm is applied to theconnector by inserting its hook 36 downwardly through the top opening 24and then upwardly through the aperture 2t, where it is releasablyretained in operative position until the wiper arm is swung over theclip to release the hook from engagement in said openings. In the modiedform of clip illustrated in Figs 7 to 12 inclusive, the clip structureis similar to that heretofore described in connection with Figs. 1 to 6,except that the top opening 24 is omitted, and the side notches or slots4l are inclined (Fig. 8) rather than vertical (Fig. 3). In this form,the respective sides of the clip may have central openings 42 and 43, tolighten the weight of the structure and facilitate manufacture.

In the modified arrangement, the spring memu ber 44 is bowed upwardly at45 intermediate its ends, said upwardly bowed portion normally engagingthe downwardly bowed or depressed portion 4B of the clip top, as shownin Figs. 9 and l0. One end of the spring engages the blade back and oneend of the clip, as shown at the left of Fig. 10, for example. Theopposite end of the spring is reversely curved to provide a latch 41,essentially similar in form and purpose to the latch 30 of Figs. l to 6.

In this arrangement, the curved end of the stud-type arm is inserted aspreviously described, and held in attached position between the upwardlybowed portion 45 of the spring and the downwardly bowed portion 45 ofthe clip top, as shown in Fig. l1.

The end of the pin-type arm is also attached, essentially as describedin connection with Fig. 5, by inserting the pin 5.8 into the inclinednotches 4i and beneath the spring latch il?, as shown in Fig. 12.

The end of the hook-type arm is applied by inserting the hook into thetransverse opening 49 which communicates with the inclined notches i,and then upwardly through the opening t in the downwardly bowed ordepressed portion of the clip top, as shown in Fig. 10.

Both forms of the clip or connector herein de scribed are simple andeconomical to manufacture, easy to assemble and attach to the wiperblade, and capable of ensuring a quick and secure attachment of theselected form of arm end which is to be removably connected to the clip.The spring element within the clip not only prevents accidental removalof the stud-type and pin-type arm ends, but also yieldingly holds saidarm ends in engagement with the connector, to prevent chattering ornoise when the wiper blade is moved across the windshield byreciprocation of the wiper arm in the usual manner.
